Dr. Neely’s research and clinical interests are in pediatric clinical pharmacometrics, including population pharmacokinetic and pharmacodynamic modeling, pharmacogenomics, simulation, and most importantly, use of models to optimize therapy for individual patients. Although Dr. Neely primarily works in the therapeutic area of infectious diseases on antiviral, antiretroviral and antifungal compounds, he has experience with other therapeutic areas. He is currently board certified in Pediatrics and Pediatric Infectious Diseases, and he is the co-Director of the Laboratory of Applied Pharmacokinetics in the University of Southern California (USC) Keck School of Medicine, working with multidisciplinary faculty collaborators in the Departments of Pediatrics, Medicine, and Preventive Medicine, in the Schools of Pharmacy and Mathematics, and the Jet Propulsion Laboratory in Pasadena, CA. With expertise in computerized drug-response modeling, he is applying his research interests to the care of his patients by operating the first HIV therapeutic drug management service at LAC+USC, which is available to all HIV providers. He also provides out- and inpatient pharmacologic consultation for a wide range of therapeutically challenging cases. In the fall of 2010, he will complete a Master’s of Science program in Clinical and Biomedical Investigations at USC, with a focus on applied Bayesian approaches to clinical trial design and pharmacokinetic modeling, and he has recently been appointed to the United States Food and Drug Administration Anti-infective Drug Advisory Committee. He has received NIH funding for most of his post-doctoral career, is the author of numerous papers and abstracts, and he is invited to give talks and workshops on dose individualization and optimization worldwide.
